WILLIAM H. POWELL, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF-ONE- HALF TO JOHN MURTHA, OF PITTSBURG, PENNSYLVANIA.

SPECIFICATION forming part 0f Letters Patent No. 729,509, dated May 26, 1903.

i Application filed February 15,*1-90'2,` Serial No.'94,l62. (No model.)

To all whom it muy concern:

Be it known that I, WILLIAM H. POWELL, a citizen of the United States, residing at Pittsburg, in the countyof Allegheny and State of Pennsylvania, vhave invented a new and useful Improvement in Steam or Water Traps, of which improvement the following is a specification.

This invention relates to certain new and useful improvements in steam or Water traps, and has for its object the provision of novel meansV whereby the valve will be automatically opened and closed under certain conditions.

The invention has for its further object to construct an apparatus of this character that will be extremely simple in its construction, strong, durable, and comparatively inexpensive to manufacture; furthermore, one that will be highly eiiicient in its operation.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had tothe accompanying drawing, forming a part of this speciiication, and wherein like numerals of reference indicate like parts upon said drawing, which shows a vertical sectional view of my improved steaml or water trap.

In the drawing the reference-numeral l indicates the water or steam inlet pipe,and 2. represents the inlet-pipe connecting tothe elbow 3, communicating with the pipe ,said pipe being secured in the casing 5. This cas# ing 5 carries an upwardly-extending port, to the upper end of which is arranged'a valve 7. Thisvcasingbl also has anvoutlet-port S' and communicating with the'outlet-port) of a slidable casing 1Q: This slidable 'casing 10 is secured to a spherical chamber 1l, which is pressed by means of av spring l2. The spring 12 has its upper end in engagement with the boss 14, which is. held in position `by the set-screw l5, extending through the boss 16 of theannular frame 17. The frame 17 is` provided at its lower end with an integralA collar 18, which is removably secured to the" casing 5.

19 indicates a valve-seat arranged in the sliding casing.

In operation the steam is forced or injected through the inlet-pipe l, following the direction of the arrows upwardly through the port 6 into the spherical chamber ll. The pressure of the steam within the said chamber will overcome the weight of the chamber and the pressure of the spring 12, and thusclose the outlet-valve until the weight of the condensed steam in the chamberll is sufficient to open the valve, whereupon the said chamber 11 will be emptied.

The many advantagesobtained by theuse of my yimproved device willV be readily apparent from the foregoing description, taken in connection with the accompanying drawing, and it will be noted that various changes may be made in the details of construction Without departing from the general spirit of my invention. Y I

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. In a device of the character described, the combinationof a casing having inlet and outlet ports formed therein, an annular frame provided-at its lower end with an integral collar,`said collar encircling the upper por tion of the said casing and being secured thereto, afvertically-arranged-pipe secured to theupper wall of the inlet-port, a valve se- Vcuredto the upper end of the said pipe, arei fof the said pipe, a receptacle, a valve-seat detachably secured on the lower end of the said receptacle, an annular frame secured to vthe saidcasing, and a spring interposed between the said frame and receptacle.

In f testimony whereof -I have hereunto signed my name in the presence of two subscribing witnesses.

WILLIAM II. rowELL.'
